Description

Technical Field

[0001] This utility model relates to the field of detection technology, specifically a portable multi-parameter rapid water quality detection device. Background Technology

[0002] Water treatment requires extensive water quality analysis, which necessitates the use of glassware such as pipettes and burettes. While conventional glassware is suitable for laboratory use, it is not ideal for field or on-site titration. Furthermore, when quantitatively titrating indicators such as chloride ions, calcium ions, hardness, and alkalinity, standard reagents in conventional titration analyses are typically calculated using volume concentrations. However, because the field or on-site environment differs from the laboratory environment, it is difficult to eliminate the influence of temperature on reagent volume, which can lead to reduced accuracy of the test results.

[0003] According to the publicized portable multi-parameter rapid water quality tester (announcement number: CN210243640U), the above application includes a box and a cover. The box and the cover are connected. The surface of the box is equipped with a display. The inside of the box is equipped with an electric heater and a heating tube located above the electric heater. The bottom of the box is equipped with a lithium battery, which is connected to the electric heater and the display. The heating tube is equipped with a closing cover that can be opened and closed. The bottom of the box is equipped with a receiving opening, a rolling device, and a telescopic device.

[0004] However, in actual use, the aforementioned rapid testing instrument requires a water sampling device to test the water quality. During use, the water sampling device must be assembled first for sampling, and then the sample is combined with the testing instrument. This increases the operation time and steps. In addition, if the water sampling device is large or heavy, it will affect the overall portability. In view of this, we propose a portable multi-parameter rapid water quality testing device. Utility Model Content

[0005] The purpose of this invention is to provide a portable multi-parameter rapid water quality testing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable multi-parameter rapid water quality testing device, comprising a handheld water quality analyzer, a data connection cable fixedly connected to the side wall of the handheld water quality analyzer, a housing fixedly connected to the bottom of the handheld water quality analyzer, and a storage component provided on the inner wall of the housing, the storage component comprising:

[0007] A sleeve is rotatably connected to the inner wall of the housing. A limit ring is fixedly connected to the inner wall of the sleeve. A take-up roller is fixedly connected to the outer wall of the sleeve. A groove is opened on the outer wall of the take-up roller.

[0008] A rotating shaft is sleeved with a sleeve, a limit block is fixedly connected to the outer wall of the rotating shaft, and a ratchet is fixedly connected to the outer wall of the rotating shaft;

[0009] A ratchet is fitted onto the outer wall of the housing. A limit frame is fixedly connected to the outer wall of the housing, and an elastic element is fixedly connected to the inner wall of the limit frame.

[0010] Preferably, the end of the elastic element away from the limiting frame is fixedly connected to the side wall of the pawl, and the pawl abuts against the inner wall of the limiting frame. The limiting frame restricts the pawl to rotate only counterclockwise, thereby limiting the rotation direction of the rotating shaft and the ratchet.

[0011] Preferably, the outer wall of the housing is fixedly connected to an outer shell, and the ratchet, pawl, elastic element and limiting frame are located inside the outer shell. The outer shell protects the ratchet, pawl and elastic element to prevent them from being damaged by external impact.

[0012] Preferably, the outer wall of the limiting block is hexagonal prism, the inner wall of the limiting ring is hexagonal prism, the outer wall of the limiting block and the inner wall of the limiting ring are in contact, and the limiting ring and the limiting block cause the rotation of the rotating shaft to drive the rotation of the sleeve and the take-up roller.

[0013] Preferably, a probe is fixedly connected to the end of the data connection cable away from the handheld water quality tester, and a lead weight is fixedly connected to the outer wall of the probe.

[0014] Preferably, the outer wall of the take-up roller has a spiral groove, and the data connection line is wound around the outer wall of the take-up roller.

[0015] Compared with the prior art, this utility model provides a portable multi-parameter rapid water quality detection device, which has the following beneficial effects:

[0016] 1. This portable multi-parameter rapid water quality testing device features a storage assembly. The linkage design between the sleeve and the rotating shaft allows for quick release of the data cable, while rewinding can be achieved by rotating in the reverse direction. When not in use, the data cable can be neatly stored, saving space and preventing cable tangling and wear, thus improving the device's portability and durability. The pawl restricts the rotation direction of the rotating shaft and ratchet, ensuring that the rotating shaft can only rewind the data cable. This unidirectional restriction ensures that the data cable maintains a stable direction during rewinding. The pawl's limit also prevents the rotating shaft from rotating in the reverse direction due to external force or vibration after rewinding, thus avoiding accidental loosening of the data cable.

[0017] 2. This portable multi-parameter rapid water quality testing device guides the winding of the data connection cable through a spiral groove. The guiding function of the spiral groove ensures that the data connection cable is arranged along a fixed path during the winding process, so that the data connection cable is evenly wound on the outer wall of the winding roller, avoiding the phenomenon of cable overlap, crossing or knotting, making the winding and unwinding process smoother, and preventing the cable from getting stuck due to disordered winding during operation.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a portable multi-parameter rapid water quality testing device, including a handheld water quality tester 1. A data connection cable 2 is fixedly connected to the side wall of the handheld water quality tester 1. The side wall of the data connection cable 2 is provided with length scale lines. A probe 4 is fixedly connected to the end of the data connection cable 2 away from the handheld water quality tester 1. A lead weight 3 is fixedly connected to the outer wall of the probe 4. A housing 5 is fixedly connected to the bottom of the handheld water quality tester 1. A storage component 6 is provided on the inner wall of the housing 5. The storage component 6 includes a sleeve 601, a limiting ring 602, a winding roller 603, a groove 604, a rotating shaft 605, a limiting block 606, a ratchet 607, a limiting frame 608, a pawl 609, and an elastic element 610.

[0025] In one embodiment of this utility model, a sleeve 601 is rotatably connected to the inner wall of the housing 5. A limiting ring 602 is fixedly connected to the inner wall of the sleeve 601. A take-up roller 603 is fixedly connected to the outer wall of the sleeve 601. A groove 604 is opened on the outer wall of the take-up roller 603. One end of the data connection cable 2 away from the side wall of the handheld water quality analyzer 1 passes through the groove 604 and is wound around the outer wall of the take-up roller 603. A rotating shaft 605 is sleeved with the sleeve 601. A limiting block 606 is fixedly connected to the outer wall of the rotating shaft 605. A ratchet 607 is fixedly connected to the outer wall of the rotating shaft 605. The outer wall of the limiting block 606 is hexagonal prism. The inner wall of the limiting ring 602 is hexagonal prism. The outer wall of the limiting block 606 and the inner wall of the limiting ring 602 are in contact. The limiting ring 602 and the limiting block 606 cause the rotation of the rotating shaft 605 to drive the rotation of the sleeve 601 and the take-up roller 603.

[0026] A pawl 609 is fitted onto the outer wall of the housing 5. A limit frame 608 is fixedly connected to the outer wall of the housing 5. An elastic element 610 is fixedly connected to the inner wall of the limit frame 608. One end of the elastic element 610 away from the limit frame 608 is fixedly connected to the side wall of the pawl 609. The pawl 609 abuts against the inner wall of the limit frame 608. The limit frame 608 limits the pawl 609 to rotate only counterclockwise, thereby restricting the rotation direction of the rotating shaft 605 and the ratchet 607. An outer shell 7 is fixedly connected to the outer wall of the housing 5. The ratchet 607, pawl 609, elastic element 610 and limit frame 608 are located inside the outer shell 7. The outer shell 7 protects the ratchet 607, pawl 609 and elastic element 610 from damage caused by external impact.

[0027] Pulling the rotating shaft 605 outwards causes the limiting ring 602 to disengage from the limiting block 606, allowing the lead weight 3 and probe 4 to be submerged in the water. The lead weight 3, carrying the probe 4, sinks downwards. The sleeve 601 and the winding roller 603 quickly rotate to release the data connection cable 2. By observing the length scale lines on the side wall of the data connection cable 2, the depth of the data connection cable 2 in the water can be observed. Then, the rotating shaft 605 is pushed to engage the limiting block 606 with the limiting ring 602. At this point, the release length of the data connection cable 2 can be precisely controlled, and the reverse rotation can be used to wind up the data connection cable 2 to accurately measure the depth of the probe 4 in the water. This allows for more efficient detection when specific water quality data is required. The linkage design of the sleeve 601 and the rotating shaft 605 allows the data connection cable 2 to be released quickly, and it can be wound up by reverse rotation. When not in use, the data connection cable 2 can be neatly stored, saving space and avoiding cable tangling and wear, thus improving the portability and durability of the equipment.

[0028] When the rotating shaft 605 is rotated in the reverse direction to wind up the data connection cable 2, the rotating shaft 605 is pushed towards the housing 5, causing the pawl 609 to engage with the ratchet 607. The limiting bracket 608 limits the pawl 609 to rotate only counterclockwise, thereby restricting the rotation direction of the rotating shaft 605 and the ratchet 607. This ensures that the rotating shaft 605 rotates in only one direction, only for winding up the data connection cable 2. This unidirectional restriction ensures that the data connection cable 2 maintains a stable direction during the winding process. The limiting of the pawl 609 ensures that the rotating shaft 605 will not rotate in the opposite direction due to external force or vibration after winding, preventing the data connection cable 2 from accidentally loosening. This keeps the cable neatly wound on the winding roller 603, improving the cleanliness of the device.

[0029] In addition, a spiral groove 8 is provided on the outer wall of the take-up roller 603. The data connection cable 2 is wound around the outer wall of the take-up roller 603. The spiral groove 8 guides the take-up of the data connection cable 2. The guiding function of the spiral groove 8 makes the data connection cable 2 arranged along a fixed path during the take-up process, so that the data connection cable 2 is evenly wound on the outer wall of the take-up roller 603, avoiding the phenomenon of cable overlap, crossing or knotting, making the take-up and release process smoother, and preventing the cable from getting stuck due to disordered winding during operation.

[0030] In this invention, during use, the lead weight 3 and probe 4 are submerged in water. The lead weight 3, along with the probe 4, sinks downwards. The sleeve 601 and the winding roller 603 quickly rotate to release the data connection cable 2, pushing the rotating shaft 605 so that the limiting block 606 engages with the limiting ring 602. This allows for precise control of the release length of the data connection cable 2, as well as reverse rotation to rewind the data connection cable 2 for accurate measurement of the probe 4's depth in the water. This enables more efficient detection when specific water quality data for a particular water layer is required. When the rotating shaft 605 is rotated in the reverse direction and the data connection cable 2 is wound up, the rotating shaft 605 is pushed towards the housing 5, so that the pawl 609 engages with the ratchet 607. The limiting bracket 608 limits the pawl 609 to rotate only counterclockwise and can only wind up the data connection cable 2. The limiting of the pawl 609 ensures that the rotating shaft 605 will not rotate in the reverse direction due to external force or vibration after winding, thus preventing the data connection cable 2 from accidentally loosening and keeping the cable neatly wound on the winding roller 603.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
